[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] In the related technology, in order to improve the indoor air quality, various air purifier products have appeared on the market. In addition to the dust removal and sterilization functions, some of these air purifiers also have humidification functions, that is, adding a humidification device to the air purifier can safely and quickly filter pollutants in the air while keeping the air at the most suitable humidity. When the water tank of the current integrated purifier and humidifier is taken out for cleaning, the residual water in the water pipe will flow directly into the machine, which may cause the machine to fail on the one hand, and also cause cleaning troubles for users on the other hand.

[0028] In view of this, an embodiment of the present application proposes an intelligent and efficient purification and humidification integrated machine based on a water stop valve structure.

[0029] See also Figure 1 and Figure 2 The intelligent high-efficiency purification and humidification integrated machine based on the water stop valve structure includes a body, a humidification tank arranged inside the body, a water tank 1 and a return pipe 2, the water inlet end of the return pipe 2 is connected to the humidification tank, and the water outlet end of the return pipe 2 is provided with a water stop valve 3.

[0030] The water stop valve 3 includes a shell 31 and a water stop valve body 32, the interior of the shell 31 forms a accommodating cavity, the shell 31 includes a main body 311, a water inlet joint 312 and a water outlet joint 313 connected together, the water inlet joint 312 and the water outlet joint 313 are vertically arranged and are both connected to the accommodating cavity; the water inlet joint 312 is connected to the water outlet end of the return pipe 2.

[0031] A sealing groove 314 is provided at the connecting end between the water outlet joint 313 and the main body 311. The water stop valve body 32 is arranged in the accommodating cavity. The water stop valve body 32 includes a core shaft 321 and a sealing portion 322. The core shaft 321 is arranged along the axial direction of the water outlet joint 313. The end of the core shaft 321 away from the water outlet joint 313 is connected to the inner wall of the shell 31 through a spring 33; the sealing portion 322 is arranged on the outer periphery of the core shaft 321 and is sealed and connected to the sealing groove 314.

[0032] A water channel interface 11 connected to the water outlet joint 313 is arranged on the side wall of the water tank 1, and a matching portion 111 abutting against the core shaft 321 is arranged inside the water channel interface 11; a matching portion is arranged at one end of the core shaft 321 that is docked with the matching portion 111, and the outer diameter of the matching portion gradually decreases from the end away from the matching portion 111 to the end close to the matching portion 111; the shape of the matching portion 111 is set to be a circular tube, and the inner diameter of the matching portion 111 is larger than the minimum outer diameter of the matching portion and smaller than the maximum outer diameter of the matching portion.

[0033] Specifically, the humidifier includes a body, a humidifying tank and a water tank 1 are arranged inside the body, a humidifying core is arranged in the humidifying tank, and the water tank 1 is used to provide water to the humidifying core so as to moisten the humidifying core and thus humidify the air. A return water pipe 2 is arranged between the humidifying tank and the water tank 1, the water inlet end of the return water pipe 2 is connected to the humidifying tank, and the water outlet end of the return water pipe 2 is connected to the water tank 1. During humidification, excess water accumulated in the humidifying tank can flow back to the water tank 1 through the return water pipe 2. A water stop valve 3 is arranged at the water outlet end of the return water pipe 2, and a water channel interface 11 is arranged on the side wall of the water tank 1. When the water tank 1 is assembled into the body, the water channel interface 11 is connected to the water stop valve 3.

[0034] The water stop valve 3 includes a shell 31 and a water stop valve body 32. The shell 31 has a hollow accommodating chamber. The shell 31 includes an integrally formed main body 311, a water inlet joint 312 and a water outlet joint 313, wherein the main body 311 is used to install the water stop valve body 32, the water inlet joint 312 and the water outlet joint 313 are connected to the main body 311 in a mutually perpendicular manner, and are communicated with the accommodating chamber, the water inlet joint 312 is used to connect with the water outlet of the return pipe 2, and the water outlet joint 313 is used to connect with the water channel interface 11 of the water tank 1, thereby forming a water channel inside the water stop valve 3, which can connect the return pipe 2 with the inside of the water tank 1.

[0035] like Figure 2As shown, the water stop valve body 32 is located in the accommodating cavity, and includes a core shaft 321 and a sealing portion 322. The core shaft 321 is coaxially arranged with the water outlet joint 313, and the sealing portion 322 is arranged on the outer periphery of the core shaft 321. A sealing groove 314 is arranged at one end of the water outlet joint 313 connected to the main body 311. The inner diameter of the sealing groove 314 is larger than the inner diameter of the water outlet joint 313, and the shape and size of the sealing groove 314 are adapted to the sealing portion 322. The sealing portion 322 can be snap-fitted with the sealing groove 314, thereby blocking the water outlet joint 313 and preventing residual water in the return pipe 2 from flowing out of the water outlet joint 313. The left end of the core shaft 321 is connected to the main body 311 through a spring 33, and the right end of the core shaft 321 abuts against the matching portion 111 set in the water channel interface 11. When assembling or removing the water tank 1, the water tank 1 moves left or right along the axial direction of the water outlet joint 313. Under the action of the matching portion 111 and the spring 33, the core shaft 321 will also move left or right along the axial direction of the water outlet joint 313, and then the sealing portion 322 connected to the core shaft 321 will also move accordingly, thereby realizing the opening or closing of the internal water channel of the water stop valve 3.

[0036] Specifically, see Figure 2 When assembling the water tank 1, use external force to push the water tank 1 into the body, so that the matching portion 111 abuts against the right end of the core shaft 321 and pushes the core shaft 321 to move to the left. At the same time, the spring 33 is compressed, and the sealing portion 322 also moves to the left and separates from the sealing groove 314, so that the water channel inside the water stop valve 3 is opened, and the excess water in the humidification tank can flow back to the inside of the water tank 1 smoothly through the return pipe 2, the water inlet joint 312, the accommodating chamber, the water outlet joint 313, and the water channel interface 11 in sequence; see Figure 3 When the water tank 1 is taken out, an external force is used to pull the water tank 1 out of the fuselage, and the matching portion 111 moves to the right along with the water tank 1. The core shaft 321 loses the thrust of the matching portion 111. At this time, the spring 33 is reset, pushing the core shaft 321 to move to the right, so that the sealing portion 322 gradually approaches the sealing groove 314 until the sealing portion 322 is completely inserted into the sealing groove 314 to achieve sealing. The water channel inside the water stop valve 3 is closed, and the remaining water in the return pipe 2 is sealed in the accommodating chamber and cannot flow out from the water outlet joint 313.

[0037] Through the above technical solution, the core shaft 321 of the water stop valve body 32 can change its position in the accommodating cavity as the water tank 1 moves, so that the sealing part 322 is sealed and connected or separated from the sealing groove 314, and then the internal water channel of the water stop valve 3 can be automatically opened or closed according to the assembly or removal status of the water tank 1, effectively preventing the residual water in the return pipe 2 from flowing out after the water tank 1 is taken out, ensuring the normal use of the machine while reducing the trouble of cleaning the residual water, thereby improving the product experience.

[0038] See also Figure 3The end of the core shaft 321 that is connected to the matching part 111 is provided with a docking part, and the outer diameter of the docking part gradually decreases from the end away from the matching part 111 to the end close to the matching part 111, so that the outer side surface of the docking part forms an inclined surface; the shape of the matching part 111 is set to be a circular tube, and the inner diameter of the matching part 111 is greater than the minimum outer diameter of the docking part and less than the maximum outer diameter of the docking part. When the core shaft 321 is connected to the matching part 111, the tip of the docking part extends into the tube hole of the matching part 111, and the matching part 111 is clamped with the inclined outer side surface of the docking part, thereby enhancing the stability of the docking between the matching part 111 and the core shaft 321, ensuring that the water channel inside the water stop valve 3 can be opened after being assembled in place, and ensuring stable and reliable assembly.

[0039] Optionally, the inner diameter of the sealing groove 314 gradually decreases from an end close to the main body 311 to an end away from the main body 311 , and a size of the sealing portion 322 is adapted to the sealing groove 314 .

[0040] For details, see Figure 2 The inner diameter of the sealing groove 314 is larger than the inner diameter of the water outlet joint 313, so as to ensure that the sealing part 322 can completely block the water outlet joint 313 after the sealing part 322 is sealed with the sealing groove 314. The inner diameter of the sealing groove 314 gradually decreases from the left end to the right end, so that the inner wall of the sealing groove 314 forms an inclined sealing surface. The shape and size of the sealing part 322 are adapted to the sealing groove 314. When the sealing part 322 is inserted into the sealing groove 314, the outer side surface of the sealing part 322 is tightly fitted with the inclined sealing surface of the sealing groove 314, thereby sealing the water outlet joint 313.

[0041] Optionally, a first sealing ring 34 is provided on a side of the sealing portion 322 facing the sealing groove 314 , and the first sealing ring 34 is sleeved on the core shaft 321 and located between the sealing portion 322 and the sealing groove 314 .

[0042] Specifically, in order to further ensure the sealing effect, a first sealing ring 34 is further provided between the sealing portion 322 and the sealing groove 314. Figure 2 As shown, the first sealing ring 34 is located on the side of the sealing portion 322 facing the sealing groove 314 and is sleeved on the core shaft 321. When the sealing portion 322 is snapped into the sealing groove 314, the first sealing ring 34 is tightly pressed between the sealing portion 322 and the sealing groove 314, which can effectively prevent water from seeping out of the gap between the sealing portion 322 and the sealing groove 314.

[0043] Optionally, the first sealing ring 34 is configured to be conical in shape.

[0044] Specifically, the first sealing ring 34 may adopt a conical structure, and correspondingly, an inclined mating surface is provided at the bottom of the sealing groove 314 for sealing with the first sealing ring 34. The sealing surface of the conical seal has a large contact area, and the sealing ring of the conical structure can automatically adjust its shape to adapt to the slight size deviation of the sealing surface, thereby ensuring good sealing performance.

[0045] Optionally, the shell 31 also includes a baffle 315, which is detachably connected to one end of the main body 311 away from the water outlet joint 313; a hollow connecting shaft 3151 is provided in the middle of the baffle 315, and the end of the core shaft 321 away from the matching part 111 is installed in the connecting shaft 3151, and the spring 33 is sleeved on the connecting shaft 3151, one end of the spring 33 is connected to the baffle 315, and the other end is connected to the side of the sealing part 322 facing away from the sealing groove 314.

[0046] In order to facilitate the installation of the water stop valve body 32 into the accommodating chamber in the housing 31, the housing 31 further includes a stop cover 315, which is arranged at an end opposite to the water outlet joint 313 and is detachably connected to the main body 311. A connecting shaft 3151 is arranged at the center of the side of the stop cover 315 facing the inside of the accommodating chamber. The interior of the connecting shaft 3151 is hollow, and the core shaft 321 of the water stop valve body 32 can be slidably installed inside the connecting shaft 3151. The spring 33 is sleeved outside the connecting shaft 3151, one end of which is connected and fixed to the stop cover 315, and the other end of which is connected and fixed to the side of the sealing part 322 facing away from the sealing groove 314. By arranging the connecting shaft 3151 inside the stop cover 315, the movement of the core shaft 321 can be guided to ensure that when the water channel inside the water stop valve 3 is closed, the moving direction of the core shaft 321 will not be lateral deviation, so as to avoid the sealing part 322 and the sealing groove 314 being unable to be completely sealed and affecting the sealing effect.

[0047] Furthermore, a second sealing ring is provided at the connection between the blocking cover 315 and the main body 311 , and the second sealing ring is used to seal between the blocking cover 315 and the main body 311 to prevent water in the accommodating cavity from leaking out through the joint between the blocking cover 315 and the main body 311 .

[0048] Furthermore, two second sealing rings may be provided, namely a large sealing ring 35 and a small sealing ring 36. Figure 4The blocking cover 315 includes an outer cover 3152, a clamping portion 3153 and an inner plug 3154 which are connected in sequence. The outer diameter of the inner plug 3154 is smaller than the diameter of the outer cover 3152. The outer diameter of the clamping portion 3153 is larger than the outer diameter of the inner cover and smaller than the diameter of the outer cover 3152. A stepped hole is provided on the main body 311 corresponding to the blocking cover 315. During assembly, the outer cover 3152 is inserted into the large hole section of the stepped hole and clamped with the stepped part, the clamping portion 3153 is clamped with the inner wall of the small hole section of the stepped hole, and the inner plug 3154 extends into the small hole section of the stepped hole. In order to ensure good sealing performance, the large sealing ring 35 is mounted on the outer periphery of the clamping part 3153 and filled between the outer cover 3152 and the step surface. The small sealing ring 36 is mounted on the outer periphery of the inner plug 3154 and filled between the outer wall of the inner plug 3154 and the inner wall of the small hole section. Through the cooperation of the large sealing ring 35 and the small sealing ring 36, a double transverse and longitudinal seal is formed at the joint between the baffle cover 315 and the main body 311, thereby enhancing the sealing effect.

[0049] Optionally, the water outlet connector 313 is plugged into the interior of the water channel interface 11 , and a third sealing ring 37 is sleeved on the outer periphery of the water outlet connector 313 .

[0050] Specifically, the shape of the water outlet joint 313 is set to be tubular, and the third sealing ring 37 is set on the outer periphery of the water outlet joint 313. When the water tank 1 is assembled into the interior of the fuselage, the water outlet joint 313 is inserted into the interior of the water channel interface 11. At this time, the third sealing ring 37 can be pressed tightly between the outer wall of the water outlet joint 313 and the inner wall of the water channel interface 11, filling the gap between the water outlet joint 313 and the water channel interface 11, thereby playing a sealing role to prevent water from seeping into the joint between the water outlet joint 313 and the water channel interface 11 during use. The third sealing ring 37 can be a tubular sealing ring, and its length and size are adapted to the size of the water outlet joint 313.

[0051] Optionally, a first chamfer is provided at the outer periphery of one end of the water outlet joint 313 that is connected to the water channel interface 11 , and a second chamfer is provided at the inner edge of the water channel interface 11 .

[0052] Specifically, when the water tank 1 is assembled into the interior of the fuselage, the water outlet connector 313 is docked with the water channel interface 11, and the water outlet connector 313 is inserted into the interior of the water channel interface 11. Figure 2As shown, the shape of the water outlet connector 313 is set to be a circular tube, and the right end of the water outlet connector 313 is the end that is connected to the water channel interface 11. The outer periphery is provided with a first chamfer, and the first chamfer forms a circle of annular first guide slopes on the outer side of the water outlet connector 313. At the first guide slope, the outer diameter of the water outlet connector 313 gradually increases from the right end to the middle. The shape of the water channel interface 11 corresponds to the water outlet connector 313 being set to be circular, and the inner edge of the water channel interface 11 is provided with a second chamfer, and the second chamfer forms a circle of second guide slopes that are concave inward on the inner side of the water channel interface 11. The first guide slope and the second guide slope can play a guiding role during assembly, reduce the assembly resistance when the water outlet connector 313 is connected to the water channel interface 11, and thus improve the convenience of assembly.

[0053] Furthermore, the intelligent high-efficiency purification and humidification integrated machine based on the water stop valve structure also includes a water stop valve bracket 4, which is installed inside the machine body. The water stop valve 3 can be installed on the water stop valve bracket 4 by screws or other fasteners, which improves the installation stability of the water stop valve 3 and is very convenient for assembly. In practical applications, a circuit interface can usually be set on the water stop valve bracket 4 to connect to the circuit inside the machine host. The water tank 1 is provided with a circuit interface of the water pump on the cover. After the water tank 1 is assembled, the circuit interface on one side of the water stop valve bracket 4 is connected to the circuit interface on one side of the cover to achieve the connection between the internal circuit of the host and the internal circuit of the water pump, so as to facilitate the control of the start and stop state of the water pump by controlling the host.

[0054] See also Figure 5 During assembly, the water stop valve 3 can be installed on the water stop valve bracket 4 first, and then the water inlet joint 312 of the water stop valve 3 can be connected to the water outlet of the return pipe 2, and the water stop valve bracket 4 can be fixed to the inside of the fuselage. Finally, the water tank 1 filled with water can be pushed into the fuselage, so that the water channel interface 11 on the box body is connected with the water outlet joint 313 of the water stop valve 3, and the circuit interface on one side of the box cover is connected with the circuit interface on one side of the water stop valve bracket 4.
